A message handwritten on notepaper sits beside an empty Corona Extra bottle amid fallen autumn leaves on the platform of the bridge.

“I love you so much Mars you brought me so much confidence from your ways.

“Beneath all the piss taking of me you were the kindest person with the warmest heart. You helped me whenever you could [and] did for so many people.

Some passersby were so touched by the tributes that they left their own messages, despite not knowing Marcello.

One wrote: “I don’t know who you are or what happened to you, but you must have been very loved! An italian guy, casually on this bridge.”

Another had left a piece of paper ripped out of a notebook tucked beneath another empty beer bottle which read: “Rip Marcelo didn’t know you personally but you looked like a pretty awesome guy! your spirit will live on forever within your friends and your family.”

Trains still roar beneath the bridge on their way to and from Bath Spa railway station.

Underneath the large red material heart, starting to disintegrate as wind rushes through the bridge railings, another handwritten note offers help.

In green ink on white paper are the words: “If you feel down please call 1-800-273-8255 we are there for YOU!”
